代谢和生物活性脂质调节因子的产生是饮食中的ω-3脂肪酸在调控过敏性炎症中发挥有益作用的关键过程。最近,有研究人员发现食用包含高水平亚麻酸(ALA)的亚麻籽油能够抑制过敏性鼻炎,具体机制是通过嗜酸性产生15-羟基二十碳五烯酸(15-HEPE)来实现抑制效果的,15-HEPE是一种二十碳五烯酸(EPA)代谢产物。在发展为过敏性鼻炎且嗜酸性细胞数据增加时,脂肪体分析阐释了15-HEPE在亚麻籽油喂食的小

代谢和生物活性脂质调节因子的产生是饮食中的ω-3脂肪酸在调控过敏性炎症中发挥有益作用的关键过程。

最近,有研究人员发现食用包含高水平亚麻酸(ALA)的亚麻籽油能够抑制过敏性鼻炎,具体机制是通过嗜酸性产生15-羟基二十碳五烯酸(15-HEPE)来实现抑制效果的,15-HEPE是一种二十碳五烯酸(EPA)代谢产物。在发展为过敏性鼻炎且嗜酸性细胞数据增加时,脂肪体分析阐释了15-HEPE在亚麻籽油喂食的小鼠中的鼻腔通道中特异富集。另外,EPA到15-HEPE的转化由嗜酸性粒细胞的15-脂氧合酶活性介导。鼻内注射15-HEPE能够通过抑制肥大细胞脱颗粒作用来抑制过敏性症状,且该过程由过氧化物酶体增殖激活受体γ的作用来介导。

最后,研究人员指出,他们的发现鉴定了15-HEPE是一个来源于EPA的、嗜酸性依赖抗过敏代谢物,为过敏性鼻炎提供了一种预防和治疗策略。
